Wonderful responsive service from Josh, Dan and all at Stack when I needed longer length spikes for my Auva 70. Virtually next day delivery w/superb comms. The Auva speaker 'pucks' have truly been superb under my B&W 805 D3 - the soundstage has opened up with more layers, the bass has become tuneful and very solid, and the music has stepped free of the drivers - more 3-D and in the room. Guitars have bite, decay, verve and with metal-strung ones a superb edge. Drums are more natural and again decay more naturally. Voices: just beautiful! Orchestral music has body, weight and power. Delightful: a joy to listen. I already had the Serene mat & stabiliser on my LP12, and hoped for similar effects with the Auva. Got that, in spades. Highly, highly Recommended!

I read the FairAudio review of the SmoothLAN products in your February newsletter, and being fairly new to digital streaming became curious about them. Other online reviews were also very positive. Since I’ve enjoyed success with your AUVA 100s, 70s and EQs, I decided to order the Regenerator. The product is absolutely amazing. The FairAudio review is spot on. There was a very pleasant immediate improvement in clarity, energy, presence and detail in the music coming via Qobuz through my pretty modest Cambridge Audio streamer and older W4S DAC. You hear and actually feel the difference. Great product well worth the investment.
As a long-time enthusiast, I am rarely surprised, but the impact of Stack Audio’s AUVA technology on my system has been a revelation.I first installed the AUVA 70 isolators under my Wilson Audio The watt Puppy 2024. The transformation was staggering. The bass response became ferocious, lightning-fast, and incredibly powerful, yet perfectly controlled. The AUVA 70s provided a rock-solid foundation that eliminated any cabinet-room smear, delivering a sense of materiality and texture I hadn't experienced before. The note decay is now fantastic—natural and lingering exactly as it should be, allowing the speakers to disappear into a surgically precise soundstage.Encouraged by this, I used the AUVA EQ (CSA 3) under my Halcro DM 88 electronics. These amplifiers are world-renowned for their ultra-low distortion, and the AUVA EQ managed to lower the noise floor even further. Micro-details now emerge from a 'jet-black' background with effortless clarity and a tangible, organic presence.Beyond the engineering excellence, the human element makes Stack Audio stand out. Josh provided world-class support—professional, passionate, and genuinely interested in my setup’s results. If you own high-resolution gear like Wilson and Halcro, these AUVA upgrades are essential.
Just added AUVA EQs for under my Rogue RP5 tube preamp and Hegel Viking CD player, and they're a high value, truly excellent addition to enhance my audio system. After reading and watching many reviews, all of which have been positive, expectations were high, for sure. But after fairly intense critical listening over several days, I can honestly say that I'm very happy with the results. The music sounds clearer, more defined, more quiet and the decays are more prominent. Bass is tighter and more clearly defined. I would have to say that the magnitude of the improvement is at the level of upgrading a component, certainly more significant than upgrading cables. At this price point, no one should hesitate to add these to their audio system. I'm now looking forward to adding AUVA 100's for my Focal Sopra 2 speakers as a next step. Dealing with Stack Audio has been a pleasure. Josh is patient, responsive, timely and helpful in his guidance, which made the purchase experience even more enjoyable. This is an extraordinary company that offers great products with a level of service and responsiveness not seen often enough in today's world.
I reached out to Stack Audio and requested 2 x sets of 4 threaded inserts for my Auva 70 feet as the ones i had for my last speakers would not fit my recently ordered new ones.I sent an email to them and the very next day they arrived.To say i was delighted is an understatment.Now i just have to wait for my speakers to arrive with the confidence that these footer will work there magic on them also.With my old speakers on a floating wooden floor the Auva 70 stopped the floor reacting like a giant drum skin resulting in blackness to the sound that encouraged more midrange and low end detail to come through i quickly realised my speakers had much greater control this resulted in a more relaxed and altogether more enjoyable sound that i wanted to listen to for hours on end.Thank you Stack Audio.
Having purchased new speakers I contacted Stack Audio and requested new studs to connect my Auva 50s to the base of my new speakers as the thread size was different between manufacturers.They arrived the following morning.I connected them up as I knew they made a huge difference on my last speakers.The difference in sound is immediate.i have a wooden floor, but they are designed to my used on a carpet if required.Using these Auva,s cleaned up the base and let me hear more of the music.I can’t stop smiling.Ambient music there is more airiness, with jazz you can hear more suttle changes.
Having researched ways to improve my system I invested in the Serene Stabiliser and a set of AUVA 70 Isolators for my KEF LS60s. The overall improvements in the sound stage, dynamics and depth are astonishing. If you want to get the best out of your system then look no further. I have just ordered a set of EQ Isolators and look forward to even more sonic delights. Customer service is exemplary and Josh could not have been more helpful in providing advice and guidance when dealing with my queries. Highly recommended.
I’ve made a few changes to my setup at the same time so in terms of sonics specifically related to the SERENE I’m not entirely sure. I was after a quality rubber mat and it’s certainly that so very happy with my purchase and I am enjoying a more detailed sound with a livelier bottom end than I had before.
Received the Auva 70s today and installed them under the Sonus Faber Liuto floorstanders. I read somewhere that they need to be broken in for about eight hours. I'm curious. The Isoacoustics Gaia 2s sounded good. I'm curious about the Auvas.Listened to this tonight. Sounds great, more music, more detail, more attack, especially with guitars, violins, and pianos. Singers, etc., are more forward and have much better placement. Highly recommended.Harrie Willems
